S300 - hydrostatic drive problems

[maciekmz250]

Hi everyone! Just since few week have 2 Bobcats under my wings. One of them makes me crazy since 2 days. The problem is a hydrostatic drive - when not loaded she goes quite good, but when skidding, or changing direction of driving she gets noisy and loses power. The rattling noise comes from under cab floor ( I think - the valve block under the seat). The other noise is a "peeeee" sound coming from drive pumps when idling, the noise fades when lever slightly moved. Did anyone of U have met such a problem? All the best

First off, have you checked your oil level?
The noise is probably the drive pumps, they make high pitched noises and control the motors, there are no valve blocks for the drive, only the lift, tilt and aux hydraulics.
Just moving it to the correct area
